i Figure l, 1s` aside view of my invention.

4Fig. 2, is a transverse vertical section of Similar'letters of reference indicatel cor-` responding parts in the several figures.

The object of this invention is to bring the weight of the car body or cause the same to bear directly over the journal boxes of the axles and at the saine time employv a swinging cross beam so as to admitof a` certain degree of lateral play or movement of the car body, independently of the trucks, substantially as hereinafter described, whereby an uneven 'wear of the journals is prevented, an easy yielding capacity given the car both laterally and ver-` tically while in motion, and much wear and tear avoided generally in the running gear and parts intimately connected therewith.

To enable those skilled in the art to :fully understand and construct my invention I will proceed to describe it.

A, represents a car truck which may be constructed in the usual or inany proper lit?, represents the wheels, C, the axles, and D, the journal boxes. j

E, is a central cross bar which connects the two sides of the truck. This cross bar is slotted longitudinally nearly its whole length and on each end of said bar a box F is placed, said boxes serving as guides for the springs G, G, which are leaf springs of semi-elliptical form, the central parts of the springs fitting in the boxes, see Figs. l, 2 and 3. The ends of the springs Gr, Gr, lit in bearings cz, a, directly over the journal boxes D, as shown clearly in Figs. l and 4.

H, H, are two metal bars the ends of which are litted on the springs Gr, G, and

extend across the truck parallel with the Be it known that i I, F. Ii'iPAnMnmx of,` j Knoxville, in the county "of `Knox and State l ofTennessee, have invented a, newfandlImproved CarlTruck for Railroad-Cars; `andl I do hereby declare that the followingism full, clear, and i exact description ofthe 1 same, reference being had to the annexed drawings, making apartfof this `specifica-1 Fig. 5, is a` `with it.` i The) bars 5H, 1H; Qajie*placedV atwsuch, 1

From the above j description `it will` bel `l seen that the weight of the car body istrans` v l I.; f mitted by the bars I, K,"L`,H, H, andlinks 85 M, to the centers of thefsprings GG,`andf j, as the ends of the latteruaretted' in they` 1"] 1 bearings a, over thefjournal `boxes 1D, thelf weight of the car is ,madetobear verticallyl i on the boxes and the journals therein are`90j prevented from wearing unevenlyaslis the i y case where the cross beam and boxes are connected in Vsuch a wayythat the `deflection f of the former will twist Ior incline thelatter i j and thereby produce an unequal bearingI of `951,` f

Neither do I claim broadly a swinging bar devised so as to give the body of the car a lateral movement irrespective of the arrangement herein shown for effecting the purpose for the weight of a car body has been transmitted to or made to bear directly over the journal boxes of the axles, as may be seen in the patent of Fowler M. Ray, March 21st, 1845. A swinging beam has also been employed for allowing a lateral movement of the car.

I am not aware that an arrangement of parts as herein shown and described has ever been devised whereby the weight of the car has been made to bear directly over the journal boxes, and at the same time a lateral movement allowed the car, both results being obtained in one truck.

I claim therefore as new and desire to secure by Letters Patent,

The arrangement and combination of the bars I, K, L, H, H, substantially as and for the purpose set forth.
